New Boiler Installation in Finchley — N2, N3 & N12

Gas Safe registered — East Finchley, Finchley Central, North Finchley & Woodside Park

Finchley’s housing is mainly 1930s semi-detached, with some Edwardian terraces in East Finchley and purpose-built flats on the main corridors. The 1930s semis are one of the most straightforward boiler installations we do — good access, predictable pipework, and a clear external wall for the flue. When the boiler in a Finchley semi reaches fifteen years old, replacement is almost always more economical than continuing repairs. We survey the property, recommend the right boiler for its size and hot water demand, and fit it within 48 hours of the survey. Supply and fit from £1,800, covering the boiler, flue, all connections, system flush, and Gas Safe certificate. Worcester Bosch and Vaillant installations come with up to 12-year manufacturer warranties., so it’s important to get it right first time.

Problem & Solution

PROBLEM → SOLUTION

If your boiler can be repaired instead. In East Finchley the Edwardian properties sometimes need pipework upgrades when switching from a system boiler to a combi — flow rates that worked for older vented cylinders are not always sufficient for modern unvented combis. We spot this on survey and price it in upfront., see our boiler repair services. We install modern, energy-efficient boilers with long warranties.

 Trustindex verifies that the original source of the review is Google. Mohammed is excellent.  He is always on time, totally professional and helpful.  My tenant is very happy, and that is important to me.  I will be using Koncore Plumbing & Heating from now on.

New Review April 2026:  Mohammed and his team have replaced my old boiler, which had reached the end of its life and had caused a leak to the property below.  A thorough investigation to check all pipework in the affected room, and removal of sodden insulation material (itchy stuff).  Boiler fully commissioned, and Hive working too.  Once again tenants are happy.  Thank you so much once again Mohammed - you are amazing and helped me out so much.

 Trustindex verifies that the original source of the review is Google. Mo & the team did a very quick and brilliant job replacing our boiler.

We have had trouble with the previous boiler for the last year and unfortunately it finally died on us.

Mo had come out previously to fix the boiler and when it eventually died we came back to him and his team.

Would highly recommend!

FAQ

Common Questions, Answered Clearly

Simple answers to help you make the right call.

Should I choose a combi, system or regular boiler?

It depends on your home's size and hot-water demand. Many Finchley semis and family homes suit a combi, while larger houses with two or more bathrooms often work better on a system boiler. We advise at your survey.

Do you remove and dispose of my old boiler?

Yes. Every fixed-price Finchley installation includes removing and safely disposing of your old boiler and any redundant parts, with a full tidy-up before we leave.

Are your engineers Gas Safe registered?

Yes. Koncore is Gas Safe registered (918817) and fully insured. Every Finchley installation is carried out by a qualified engineer and notified to Building Control on your behalf.

How much does a new boiler cost in Finchley?

Our fixed-price installations in Finchley start from £1,800 supplied and fitted. The final price depends on the boiler and any pipework changes, and we confirm it upfront after a free survey, so the price we quote is the price you pay.

How long does a new boiler installation take?

A straightforward combi swap in Finchley is usually completed in a single day. A system change or a first-time install can take two to three days, and we confirm exact timings at your survey.

Do you offer same-day or next-day boiler installation in Finchley?

Yes. Subject to availability we can often survey your Finchley home and fit the new boiler the next day, sometimes the same day. Call 020 7108 6322 to check the soonest slot.
